摘要: 以籼稻保持系珍汕97B和粳稻保持系辽91B为亲本,构建了一个包含176个单株的F2群体及123个SSR标记的遗传图谱,在3种环境下联合检测控制花粉育性和小穗育性的QTL。共检测到3个控制花粉育性的主效应(加性效应和显性效应)QTL(qPF3、qPF5和qPF6)和4个控制小穗育性的主效应QTL(qSF3、qSF5、qSF6和qSF8),其中qPF5与qSF5、qPF6与qSF6均为同一个QTL,为重要的育性QTL。另外,检测到3对花粉育性和4对小穗育性QTL间互作,说明上位性效应对籼粳杂交后代的育性具有重要作用。

Abstract: An F2 population consisting of 176 individuals was developed from a cross between an  indica  maintainer line Zhenshan 97B and a japonica   maintainer line Liao 91B and a genetic map containing 123 SSR markers was constructed based on the population. Pollen fertility and spikelet fertility were investigated in three seasons. Three maineffect (additive effect and dominant  effect) quantitative trait loci (QTLs) for pollen fertility (qPF3,  qPF5 and qPF6) and four maineffect QTLs for spikelet fertility (qSF3, qSF5, qSF6 and qSF8) were detected. Among them, qPF6 and qSF6,   and qPF5 and qSF5, important QTLs for rice fertility,  were mapped on  the same locations.   In addition, three pairs of QTL interaction for pollen fertility and four pairs for spikelet fertility were detected, suggesting that epistatic effects play important roles in the fertility of indicajaponica hybrids.

Key words: rice, indicajaponica hybrid, quantitative trait locus, pollen fertility, spikelet fertility
